New population of 200 of world’s rarest orangutans discovered on Sarawak

Wildlife Conservation Society (WCS) congratulates Government of Sarawak for protecting globally significant orangutan population

April 2013. A new population of rare orangutans has been found in an area of about 14,000 hectares (140 sq km) in Ulu Sungai Menyang, close to Batang Ai National Park in Sarawak. Local Iban communities had been aware of the existence of orangutans in this area, but until recently no major research had been conducted in Ulu Sungai Menyang.

Just 3 – 4,500 known to exist

The sub-species of orangutan, Pongo pygmaeus pygmaeus, is listed as the most severely threatened orangutan worldwide with a total of between 3,000-4,500 animals, of which 2,000 live in Sarawak in Batang Ai National Park and Lanjak-Entimau Wildlife Sanctuary.

The Wildlife Conservation Society congratulates the Government of Sarawak for protecting a globally significant population of up to 200 of the world’s rarest Bornean orangutans recently found by a team of conservationists in Sarawak, Malaysian Borneo.

Melvin Gumal, Director of Wildlife Conservation Society, Malaysia Program, said: “It is indeed wonderful to hear the Government’s initiative towards protecting these orangutan and their habitat especially when preliminary scientific data indicates the existence of a globally significant population.”

Central Borneo

Field surveys were conducted in February by staff from the Sarawak Forest Department, assisted by Sarawak Forestry Corporation, Wildlife Conservation Society and Borneo Adventure. The surveys covered 248 kilometres (154 miles) of transects in the hilly, undulating terrain in central Borneo. Ground surveys were supplemented by data from aerial surveys so that 80 percent of the study area was covered.

995 nests found

A total of 995 nests were found in the area. Fresh nests were found in all transects as well as in the remote areas covered by the aerial surveys indicating recent use of the area by these rare orangutans.

Highest level of protection

Upon confirmation that the area had a globally significant population of the rare sub-species, the Government of Sarawak officially indicated the need to protect this area in perpetuity. It is already a High Conservation Value Forest, considered to have an area of high biological, cultural, economic and livelihood significance.

The Sarawak Government intends to hold a dialogue with local communities and the other key stakeholders to discuss options and to involve them in any conservation effort in the area. The four organizations involved in the survey will conduct a follow-up study in the area to formulate strategic actions involving all stakeholders including the local communities.

WCS orangutan conservation work in the Batang Ai – Lanjak Entimau landscape is supported by the U.S. Fish and Wildlife Service’s Great Apes Conservation Fund.

Huge population of tapir discovered on Peru – Bolivian border

Paradise found for Latin America’s largest land mammal – WCS documents at least 14,500 lowland tapirs thriving in Peru and Bolivia‘s Madidi-Tambopata Landscape

January 2012. Wildlife Conservation Society (WCS) scientists have documented a thriving population of lowland tapirs – the strange forest and grassland-dwelling herbivore with the trunk-like snout – living in a network of remote national parks spanning the Peru-Bolivia border.

Camera traps

Using a combination of camera traps, along with interviews with park guards and subsistence hunters, WCS estimates at least 14,500 lowland tapirs in the region. The population bridges five connected national parks in northwest Bolivia and southeastern Peru. The study brings together 12 years of research on lowland tapirs in the region. Together with WCS studies on jaguars, the results underscore the importance of this protected area complex for the conservation of Latin America’s most charismatic terrestrial wildlife species.

Madidi-Tambopata

“The Madidi-Tambopata landscape is estimated to hold a population of at least 14,500 lowland tapirs making it one of the most important strongholds for lowland tapir conservation in the continent,” said the study’s lead author Robert Wallace. “These results underline the fundamental importance of protected areas for the conservation of larger species of wildlife threatened by hunting and habitat loss.”

Largest terrestrial mammal in South America – Threatened by habitat loss and hunting

The lowland tapir is the largest terrestrial mammal in South America, weighing up to 300 kg (661 pounds). Its unusual prehensile proboscis or snout is used to reach leaves and fruit. Tapirs are found throughout tropical forests and grasslands in South America. However, they are threatened by habitat loss and especially unsustainable hunting due to their large size, low reproductive rate (1 birth every 2-3 years), and ease of detection at mineral licks in the rainforest. Lowland tapirs are considered Vulnerable by the IUCN.

WCS collected and systematized 1,255 lowland tapir distribution records in the region. These records came from research observations and camera trap photographs as well as interviews with park guards of Madidi, Pilón Lajas and Apolobamba National Parks in Bolivia, and Bahuaja Sonene and Tambopata National Parks in neighboring Peru, and subsistence hunters from 19 Takana and Tsimane’ communities.

Camera trap data revealed that lowland tapir abundance was higher at sites under protection than sites outside protected areas. At one site sampled over time, the Tuichi River, camera trapping has revealed that lowland tapir populations have been recovering following the creation of Madidi National Park in 1995. Prior to the creation of the park, loggers had hunted heavily in this area.

Madidi National Park

Madidi National Park contains 11 percent of the world’s birds, more than 200 species of mammals, 300 types of fish, and 12,000 plant varieties. The 19,000 square-kilometre (7,335 square mile) park is known for its array of altitudinal gradients and habitats from lowland tropical forests of the Amazon to snow-capped peaks of the High Andes.

Working with government partners in Bolivia and Peru, the Greater Madidi-Tambopata Landscape Conservation Program aims to develop local capacity to conserve the landscape and mitigate a variety of threats to biodiversity and wildlife including lowland tapirs, including road construction, logging, unsustainable natural resource use, and agricultural expansion.

Julie Kunen, WCS Director of Latin America and Caribbean Programs said: “WCS commends our government and indigenous partners for their commitment to the Madidi-Tambopata Landscape. Their dedication is clearly paying off with well-managed protected areas and more wildlife.”

WCS’s conservation research in the Madidi-Tambopata Landscape has been made possible by the Gordon and Betty Moore Foundation, The John D. and Catherine T. MacArthur Foundation, the blue moon fund, USAID, the Beneficia Foundation, the Disney Worldwide Conservation Fund, Woodland Park Zoo, and other generous supporters.

The WCS findings were described in the December issue of the journal Integrative Zoology. Authors include Robert Wallace, Guido Ayala, and Maria Viscara of WCS’s Greater Madidi-Tambopata Landscape Program.

February 2013. The Critically Endangered subspecies of Colombian Tapir has been rediscovered in the Paujil Nature Reserve after being considered extinct in the Magdalena Valley rainforests of central Colombia. Camera trap photos and fresh tracks of this rare creature from the Paujil Reserve demonstrate that the purchase and active protection of the last remnant of rainforest in the Magdalena Valley can make a real difference to saving species on the edge of extinction: here.

New species in Borneo

Sunday, September 23, 2012 9.9

A team of international scientists has discovered on the Southeast Asian island of Borneo at least three species which are new to science. The Dutch expedition leader Menno Schilthuizen of Naturalis Biodiversity Center announced that this Sunday on Vroege Vogels radio. They are two carrion beetle species and a new damselfly. Because they have just been discovered they have not yet been named.

The scientists have already been in Borneo for weeks to investigate the thousands of endemic plants and animals which are found there. The heart of the expedition is the famous Mount Kinabalu, with its 4095 meters one of the highest peaks in Southeast Asia. Central question is how all these unique species have evolved here. Among the 40 scientists from Naturalis and the Malaysian Sabah Parks conservation organization, there are insect experts, bird watchers, botanists, amphibian specialists and snails researchers.

Besides the carrion beetles and dragonfly, also a new site was discovered where the rare pitcher plant (Nepenthes edwardsiana) grows. This carnivorous plant is only found on Mount Kinabalu. According to Schilthuizen this is a unique and important find.

The English language blog of the expedition is here.

October 2012. At the conclusion of a large scale expedition on the island of Borneo, researchers of the Malaysian nature conservation organization Sabah Parks and Naturalis Biodiversity Center in The Netherlands collected some 3500 DNA samples of more than 1400 species. Among these are approximately 160 species new to science: here.

Malay Archipelago Bat Not One, but Two Species

(Sep. 6, 2012) — Genetic studies of Myotis muricola, otherwise known as the Wall-roosting Mouse-eared bat or Nepalese Whiskered Myotis, suggest that it consists of not one, but two distinct species.

M. muricola is widespread on the Malay Archipelago, a region with an island geography that provides natural boundaries and as a result displays some of the richest biodiversity in the world. Until now scientists had compared the shape and size of Myotis bats across the Archipelago and conducted only limited DNA analysis. As a result the Myotis family tree has remained in disarray with often contradictory lines of evidence confusing matters.

To resolve these taxonomic difficulties, a team from the Universiti Malaysia Sarawak and the Indonesian Institute of Sciences launched the first in-depth genetic study on M. muricola and its sister taxa, M. mystacinus. Writing in the Pertanika Journal of Tropical Agricultural Science, the team describe how they examined the bats in two regions, West and East of Wallace’s line … . Using a genetic analysis technique known as ‘DNA cytochrome b sequencing’ …, they found that the Western and Eastern groups had a genetic distance of between 26 and 39 per cent.

Based on this high genetic distance they argue that M. muricola Eastern and M. muricola Western should be considered as two distinct species. The data also suggest that the Eastern bat started to diversify in the western region during the Pliocene (5 to 2.5 million years ago). They became fully diverged within the western region during the Pleistocene (2.5 million to 11,000 years ago) under the influence of ancient Sunda River systems that had produced gallery forest corridors which functioned as safe havens for the bats as the climate and geography around them changed.

The authors stress that as a result of these findings an official revision of the taxonomic status of M. muricola is urgently needed. In addition, more samples from throughout the geographic range are required to firmly establish these findings.

Heart of Borneo expedition


Mount Kinabalu friendly warbler

The Mount Kinabalu friendly warbler is also known as the friendly bush warbler (Bradypterus accentor).

This bird species occurs only in Malaysia, in the surroundings of Mount Kinabalu of Borneo island.

This is one of the animals, plants, and fungi which the Heart of Borneo expedition will probably see this September. But maybe they will discover species, new to science. And they may find out how the unique species of Mount Kinabalu and the mountains around it evolved.

What are people packing for that expedition? See here.
